@undercover_snail No problem. Your stories seem really interesting. I'll definitely start reading them when I'm not super busy :)
To be honest, I'm not sure how I keep all my languages in my head, either. And German isn't as hard as you think it is. It shares a language family with English and it's written phonetically, so it's easy to pick up new vocabulary. My German still kind of stinks (it's been awhile since I've focused on it) but I picked it up a lot easier than any of the other languages I've tried learning. You just need to be patient with yourself and if you want to learn German for the right reasons, you'll get it.
